Motor Drivers

Motor Drivers Four characteristics are required for motor drivers ■ High Reliability ROHM is further strengthening the internal protection capabilities of its motor drivers, such as by integrating functions that prevent malfunctions due to voltage drop and protecting the IC from abnormal voltages and currents. We are also implementing a current limiting function that controls High Reliability the motor current at startup, during forced stops, and when locked. In addition, function pins are provided that output fault conditions to an external host processor, ensuring a greater level of safety....

ROHM brush DC motor drivers are reversible drivers equipped with functions such as PWM, brake, and forward/reverse modes and drive brush motors using an H bridge circuit. These high efficiency, high reliability motor drivers are offered in a range of voltages, currents, and package types - including pin-compatible models. Vref Control Function PWM drive at the output stage is enabled by supplying a DC voltage to the Vref pin. Changing the PWM ON duty based on the supplied DC voltage value makes it possible to control motor speed. This method (PWM duty control) results in lower power consumption...

Stepper Motor Drivers ROHM's high efficiency, high reliability CLK-/PARA-IN stepper motor drivers are available in a range of interfaces, voltages, currents. Pin-compatible models are offered as well. When the motor current decays, the followability of the current will worsen depending on the current regeneration mode (Slow/Fast Decay), causing vibration and noise. As a countermeasure, a Mix Decay function is built in that externally Current Distorted adjusts the ratio of Slow Decay and Fast Decay during current attenuation. SLOW Decay SLOW Decay Current Regeneration Region Advantageous for torque...
